The relation between musical abilities and speech prosody perception: A meta-analysis

Previous research has suggested a relationship between musical abilities and the perception of speech prosody. However, effect sizes and significance differ across studies. In a meta-analysis, we assessed the overall size of this relation across 109 studies and investigated which factors moderated the effect. We found a significant, medium-sized positive correlation between musical abilities and speech prosody perception. This correlation was larger for studies on non-native compared to native prosody perception. We attribute this difference to ceiling performance in native perception, while non-native perception may be more difficult and can thus be facilitated by musical abilities. In addition, prosody perception was more strongly correlated with music perception than with music training, possibly because training metrics disregard untrained individuals with naturally strong musical abilities. Further analyses showed a stronger correlation for prosodic pitch compared to prosodic timing perception, and a stronger correlation for behavioural accuracy measures compared to reaction times. We did not find differences in effects between linguistic and emotional prosody, between L1 tone language users or non-tone language users, or between adults and children. This meta-analysis generally supports theories proposing a connection between music and speech prosody. Furthermore, this study highlights the potential importance of individuals’ musical abilities for the acquisition of second language prosody.
